[mapserver-users] Widely spaced Diagonal Fill

[Stephen Lime]

Try:

  SYMBOL
    NAME 'crosshatch'
    TYPE VECTOR
    POINTS
      0 0
      1 1
    END
  END  

then in your class

  SYMBOL 'crosshatch'
  SIZE 5 # or whatever

Chip,

in the CLASS section you can use the SIZE tag for the size
(height/width/spacing) of the  symbol. That should do what you want. You can
also do a scale-dependend fill pattern with the tag SYMBOLSCALE in the LAYER
section, but that effects all symbols and labels for the layer.

BTW: If somebody succeeded in creating a diagonal fill with a more than
one-pixel-wide fill line it would be nice to submit the example.
